FEEDING AND WEIGHING MACHINE.

SPECIFICATION forming part of Letters Patent No. 628,879, dated July 11,1899.

Application filed January 3, 1899. Serial No. 700,899. (No model.)

To [bl Z whom, it may concern-.-

Be it known that I, PIERRE C. \VARING, a citizen of the United States,residing in Yonkers, in the county of Vestohester and State of NewYork,have invented certain new and useful Improvements in Feeding and\Veighing Attachments for Hat-Making and other Machines, of which thefollowing is a specification.

This invention relates to an improved feeding and weighing attachmentfor hat-making and other machines in which a determined quantity of fur,wool, or other fibrous material is weighed otf and fed forward at suchpredetermined periods of time as may be necessary for the proper workingof the hat-making or other machine to which it is attached, theimprovements being designed with a view of interrupting the supply offibrous material as soon as the required quantity issupplied andreturning said fibrous material to the main hopper of the feeder duringthe time between the complete weighing of the determined quantity offibrous material and the expiration of the predetermined interval whenit is to be delivered to the machine, after which the parts are restoredto their normal position ready for the next weighing op eration.

My invention consists of a feeding and weighing mechanism for hat makingand other machines in which the feeding and weighing mechanisms areoperated in combination with an oscillating deflector that returns thefibrous material to the feed'hopper upon the weighing of a predeterminedquantity of material.

The invention consists, further, of the com 'bination,with the feedingand weighing mechanisms, of an oscillating deflector and means foractuating it at the proper time, so that the supply of fibrous materialto the weighing de vice is interrupted and the material returned to thefeed-hopper until the charge is delivered and the movable part of theweighing device returned to its normal position.

The invention consists, further, of certain details in the constructionof the deflector and its operating mechanism and the means forpositively moving the deflector, as will be fully described hereinafterand finally pointed out in the claims.

In the accompanying drawings, Figure 1 represents a side elevation of myimproved feeding and weighing attachment for hatmaking and othermachines. Fig. 2is a vertical longitudinal section of the same. Fig. 3is a detail side view showing the mechanism for operating the deflector,drawn on a larger scale. Fig. 4 is an end elevation of the same, partlyon line 4. 4, Fig. 5; and Figs. 5 and 6 are diagrams showing thedifferent positions of the deflector and its operating parts.

Similar letters of reference indicate corresponding parts.

Referring to the drawings, A represents the feed-hopper of my improvedfeeding and weighing attachment for hatmaking and other machines. In thefeed-hopper A is arranged an endless belt or apron B, provided withprojecting pins, by which the furor other fibrous material which issupplied to the 110pperis fed to the weighing device. Rotary motion isimparted to the endless feed-belt b by a beltand-pulley transmissionfrom the driving shaft S. The fur or other fibrous material is clearedfrom the supply-apron bya clearing-roller O and wiper G, by which thematerial is conducted over an inclined plate D into the box E of theweighing de vice. closed by a movable platform E, which is applied to afulcrumed end-weighted lever The platform E is held in norm ally-closedposition below the box E by a fingerfat the end of a fulcrum'ed andweighted lever F, which swings on knife-edges and the weight of which isso adjusted that the required quantity of fibrous material is weighedoff. The fingerf is pivoted to the front end of thecounterbalancing-lever F and tapered at its lower end, so that theplatform E can return into its normal closed. position after deliveringthe quantity of fibrous material weighed thereon, the finger givingsufficiently to permit the passage of the platform below the box E, soas to close the same, as shown in Fig. 1.

The parts so far described are well known, and I do not claim the same.

The novel feature of my present invention consists in the arrangement ofa deflecting mechanism, by which the supply of fibrous material to theweighin g device is interrupted and the fibrous material returned intothe The box E is open at the bottom and -oted finger 71 feed-hopper assoon as the required quantity is weighed off, the return of the fibrousma terial to the feed-hopper being kept up while the quantity weighedoff is being delivered to the hat-forming cone or other mechanism anduntil the platform of the weighing de vice is returned into its normalposition at the lower end of the weighing-box E.

It is evident that the supply-stream of fibrous material will vary involume according to the greater or smaller quantity that is in thefeed-hopper and also that the supplystream is heavier when a freshsupply of fibrous material is put in the feed-hopper than when it hasbeen more or less broken in smaller pieces by the working it receives inthe feed-hopper and the action of the wiper therein. It is furthermoreevident that the natural result of a supply-strean'i of an uninterruptedcontinuousand constantly-varying volume would be the varying of adesired quantity of material at irregular intervals and the desiredquantity of material would be only approximately correct.

The object of this invention is to provide an attachment for thosemachines operating on fibrous material which require an absolutelyaccurate quantity of material to be delived only at predeterminedintervals. The important point is that the delivery of theaccurately-weighed fibrous material should be timed properly for themachine, so as to be worked up by the machine to which it is applied.This is accomplished by arranging in connection with the feeding andweighing devices an automatically-operated deflector G, which isfulcrumed in a notched arm g above the weighing-box E and extended indownward direction into the upper part of the box, as shown in Figs. 1and 2. The pivot of the deflector G is provided with a crankarm g, whichis connected by a cord with a fuicrumed counterbalancing-lever H,located below the counterbalanced weighinglever E and provided at itsend with a piv- On the shank of the lever H is arranged a grooved blockH, which can be adjusted by a set-screw h on the shank of the lever H,said block H being provided with a side groove 7L2, that is engaged byan inwardly-bent end 7L3 of a fulcrumed and weighted lever H which isarranged on the side of the feedhopper below the block H, as shownclearly in Fig. 3. The fulcrumed lever H is intermittently engaged by apin i, that is carried by a pulley 'i, which is located below thefnlcrumed lever H and which is driven by a belt-and-pulley transmission2' i, which receives motion from a pinion 2' and gear-wheel 2"", asshown in Figs. 1 and 3. The pinion is placed on the shaft of theconveyer l, on which the fibrous material is discharged from theweighing-platform E.

The operation of my improved deflecting attachment is as follows: Assoon as the quantity of fibrous material which is to be weighed off isfed to the weighingdevice the platform E is dropped past the end of thecounterbal-; ancing-lever F and passed on to the projecting finger 72 ofthe fulcrumed lever H, which extends more into the path of the platformE than the finger-f of the weighted lever F. The platform E moves thelever H immediately in downward direction until the projecting portionof the block H abuts against the upper inwardly-bent end of the lever Has shown in Fig. 5. By the downward motion of the lever H the deflectorG is oscillated from its vertical position into the inclined position,as shown in full lines in Fig. 5, so that. the supply-stream of fibrousmaterial is not delivered into the weighing-box E, but defiectedinstantly into the feed-hopper A, as I shown by the arrowin Fig. Theweighted lever H rests on the end if of the lever I'I until the pin i onthe pulley i engages the lower part of the lever H and lifts the latter,so that the upper end If moves into the grooved portion of the block H,by which the immediate release of the weighirig-platform E is producedand the quantity weighed off delivered to the conveyer I. Simultaneouslytherewith the weighted lever H is retained by the weighted lever H untilmoved entirely clear of the grooved portion of the block l-l into theposition shown in Fig. (3, and the up per end 71' is released from thegrooved block H, so that the lever H can be returned into normalposition and follow the weight of the deflector G, which latter isreturned by gravity into its normal vertical position. (Shown in fulllines in Figs. 1 and 2.) The return motion of the deflector Galso returns the weighted leverHinto normal position. As the platform E isreturned into normal position at the lower end of the weighing-box Ebefore the return of the deflectorinto its normal position it is readyto receive the next supply of fibrous material. As the pin 6 of thepulleyt" has in the meantime been released from the shank of theweighted lever Hhthesame is likewise returned into normal position readyfor the next operation.

My improved weighing attachment not only interrupts the supply offibrous material to the weighing device as soon as the required quantityis weighed off, but also interrupts the feeding of the fibrous materialfor a cer tain predetermined interval of time, so that the quantityweighed oif and delivered to the machine is worked oil before the nextsupply of fibrous material is delivered. This is an important. feature,as thereby the weighed supply of fibrous material to the machine can beaccurately and reliably timed according to the requirements of themachine.

Having thus described my invention, I claim as new and desire to secureby Letters Patent- 1.
